hairy root | green hairy root cultures. Hairy roots cultures of Daucus carota turn green under continuous illumination, while the content of the major phenolic compound 4-hydroxybenzoic acid is reduced to half as compared to normal hairy roots cultured in darkness. 4-Hydroxybenzaldehyde dehydrogenase (HBD) activity is suppressed in the green hairy roots and 15fold less compared to normal hairy roots. Volatile analysis of 14-day-old green hairy roots reveals higher monoterpene and sesquiterpene contents than found in normal hairy roots, methyl salicylate content is higher in normal hairy roots than in green ones, overview | Daucus carota | - |
